In an interview with Elvis Duran and the Morning Show on Tuesday, Zayn revealed: "The interesting thing was, she is friends with Gi, so she already reached out after hearing it because [producer] Jack [Antonoff] had just played her the song anyway and she went in the studio the next day to record it.

"She mentioned to me that she liked the song and I already kind of knew in the back of my head that she liked it.

So I asked her if she wanted to be on it and she was cool with it."

Pop princess Taylor, who has been keeping a low profile since her 1989 world-tour came to an end last year, is clearly a huge fan of Zayn's distinctive voice.

Promoting the video, Taylor said : "I think Zayn's voice is one of those that is really rare.

"He is very special and wonderful."

Taylor Swift's new album is HEAVILY rumoured to be on the way very soon.
